On system update: "python-gast03 and python-gast are in conflict"

Question

Trying to make a system update to upgrade Tensorflow:

sudo pacman -Syu

I am asked:

:: python-gast03 and python-gast are in conflict. Remove python-gast? [y/N]

I say No:

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: python-gast03 and python-gast are in conflict

I then try to remove the oldest of the packages:

sudo pacman -R python-gast03

and I get:

error: target not found: python-gast03

So, where does this conflict come from if the oldest package is not even present?

Answer 1

I had the same issue when updating my system.

sudo pacman -Syu

I tried removing python-gast.

sudo pacman -R python-gast

I was told that python-tensorflow-opt-cuda was dependent on that package. So, I updated it.

sudo pacman -S python-tensorflow-opt-cuda

It replaced gast with gast03 at that point. Then, I could do a system update.

sudo pacman -Syu

Everything worked as expected after that.

Answer 2

What worked for me was running

sudo pacman -R python-gast

and then updating whatever the dependency was.

In my case the command was

sudo pacman -S python-tensorflow

This will tell you that there is conflicts and give you an option to remove the outdated one.

and then you can run the update just fine.

Answer 3

I am on BlackArch.
I faced same issue, then I uninstalled python-gast and other dependencies along with it.
And then, I upgraded system and then reinstalled it.
Have a try?

Answer 4

Someone already made a bugreport for pacman:

https://bugs.archlinux.org/task/64785

Steps to solve the problem can be found in the report:

pacman -Sy python-tensorflow

pacman -Syu

Answer 5

I think it's because tensorflow was built on python-gast 0.3.x version. now python-gast updated to 0.4 version, but the new version of tensorflow still based on 0.3.x which was rename to gast03. So remove "python-gast(which will update to 0.4 version)" and update tensorflow(which will install python-gast03 automatically) would do the trick.
